다국어 초록 (Multilingual Abstract)

Background/Aims: As little is known about asymptomatic patients with erosive reflux esophagitis, this study aimed to evaluate the characteristics of subjects with erosive reflux esophagitis who were diagnosed by endoscopy in a routine health check-up program. Methods: We prospectively recruited the subjects who had erosive reflux esophagitis (≥LA grade A) among those who visited a health promotion center for routine check-up. We performed a case-control study to evaluate the clinical characteristics and risk factors of reflux esophagitis. Results: The enrolled study participants comprised 264 subjects with erosive reflux esophagitis and 245 healthy controls. All subjects with erosive esophagitis had LA grade A (85%) or B (15%). Eighty percent of all subjects (N=264) with erosive esophagitis did not have frequent reflux symptoms. Using a multiple logistic regression analysis, erosive reflux esophagitis was associated with smoking (odds ratio (OR), 2.8; 95% confidence interval (CI), 1.7-4.4), and BMI (OR, 1.2; 95% CI, 1.1-1.3). Subjects with symptomatic erosive esophagitis had higher psychosomatic symptom scores than asymptomatic subjects did. Conclusions: Only 20% of subjects who were diagnosed with erosive esophagitis at their routine check-up had frequent reflux symptoms. Symptomatic erosive esophagitis was associated with psychological factor. (Kor J Neurogastroenterol Motil 2006;12:12-18)
